This tab enables the administrator to update and view the overall security arrangements for Clash Manager. For details of the security arrangements, refer to Access Rights.

The tab essentially displays one of four panes for setting Security Levels (namely, Status, Owner discipline, Check CE, and Comments), or a dialog box called 'User Access Levels' for setting the User Access Levels. The particular security level pane, or the dialog box, is selected by clicking on the appropriate icon in the row across the top of the tab.

The elements displayed in the centre of the pane, depend on whether the pre-defined or custom settings are being used. When pre-defined settings are being used, a slider control enables the security to be set to one of the five states namely, High, Medium High, Medium, Medium Low and Low. The name of the selected state and a narrative statement of its effect appear to the right-hand of the slider control. The default state for each security level is Medium. When custom settings are being used, the pane displays the message: 'Custom - To change the settings, click Custom Level - To use the recommended settings, click Default Level'.

At the bottom of the pane are two buttons. The Custom Level button leads to the 'Clash Manager - Security Settings' form, at which the pre-defined settings for the particular Security Level can be superseded by custom (user-defined) settings. The Default Level button is for selecting the default state.

This dialog box is for selecting Users and their access levels. It displays a single pane on which the access arrangements are shown in tree format. The major nodes of the tree are Users and Disciplines.

User membership of a discipline is granted by dragging the discipline and dropping it onto a user name. Alternatively, the discipline can be selected from a right click menu. Similarly, a user name may be dropped onto a discipline.

A checkbox is located against the left-hand side of each user and discipline symbol. Supervisor rights are shown in the tree by a checked box against the discipline under the user and by a checked box against the user under the discipline.
